80 Keysight EXG and MXG X-Series Signal Generators User’s GuideOptimize PerformanceUsing the Power Meter ServoPower Meter Servo ConfigurationThe following procedure is a basic configuration for using the signal generator’s Power Meter Servomode.1. Connect the equipment as shown in Figure 4-15.Figure 4-15 Power Meter Servo Configuration2. Set the signal generator frequency and amplitude to the desired settings for your device.3. On the signal generator, press AMPTD > Leveling Control > Power Meter Servo Configuration.4. Press Channel A Setup and configure the power meter. Refer to Configuring the Power SensorChannels on page 71.5. Press Return > Return > Settling Error. Set the Settling Error value.6. Press Return > Return > Leveling Mode. Select the leveling mode.Power Meter Once performs the adjustment only at the end of any transition (amplitude orfrequency change). After the adjustment is performed and the power is corrected, no furtheradjustments are performed until the next transition.The configuration described below is one possible setup example.Consider the limits of your DUT and use caution to protect the DUT frombeing exposed to too much power.To get the best results and reduce stress on the DUT, the amplitude offsetshould be set to match the approximate gain of the device. For example, ifthe DUT is an amplifier with 20 dB of gain, set the amplitude offset to 20dB.Press AMPTD > More > Amptd Offset, then enter a value.For details on each key,use key help as describedon page 40.Power SensorDirectional Coupler
